This is a multi-step process. First, one has to find out how
to restore associations in general, i.e. independently of MSI.
Where should one store, on install, the information what the old
association was? What if there already is "old" extension
information?

This is general Win32 stuff, and I don't know what the answer is.

Then, how can this be integrated into an MSI file? Perhaps
MSI already offers built-in mechanism for that, perhaps existing
mechanisms for dealing with the registry have to be used.

This is MSI specific, and is likely answered in the Microsoft
MSI documentation.

Then, finally, how can the Python script be changed to invoke
the MSI mechanism? This is very easy: If you know what tables
in MSI to manipulate in what way, the relevant Python code
should become easily apparent.

So in this case, I don't think any amount of documentation on
the Python script will help to solve this problem (that is
not to say that documentation should be avoided for this reason,
of course).
